Application filed December 29, 1915. Serial No. 69,201.

To all whom it may concern Be it known that we, DAVID HIBBnR'r. 'THOMAS, chemist, ARTHUR DOUGLAS Bnnn,

chemical engineer, and FREDERICK JOHN MORGAN, mechanical engineer, subjects of the King of Great Britain, residing at 56 VVaun road, Morriston, Glamorganshire, Wales, 1 Fenchurch avenue, London, E. G, England, and 30 Wind street, Swansea, Glamorganshire, Wales, respectively, have invented new and useful Improvements in and Relating to Spray-Producers or Atomizers for Liquids; andwe do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to spray producers or atomizers.

The object of the invention is to provide an improved construction of spray producer or atomizer whereby acids and corrosive chemicals can be efliciently and effectively atomized without the presence of drip at the point of atomization. To this end we employ converging channels having nozzles at their outer ends for the conveyance of a gas under pressure such as steam or compressed air together with means for delivering the material to be atomized upon the surface of the gas conveying members and allowing said material to flow along the surface of these members under the influence of gravity until it reaches the point of atomization and is acted on by the gas issuing from the aforesaid nozzles.

To enable the invention to be more fully understood the same will now be described by aid of the accompanying drawings, in which Figures 1 and 2 are a side and edge elevation respectively of the invention, and Fig. 3, a modified form of the invention.

Corresponding parts are referred to by similar letters of reference throughout the specification.

Referring to Figs. 1 and 2, the device is shown as comprising a main tube a which is divided at its lower end into two branches (4' and a provided at their extremities with nozzles M which converge at their delivery end. Upon the upper end of the tube a is a collar 0 by which the whole is secured by suitable means to the gas pressure supply.

The pressure may be any convenient fluid such as compressed air or steam which when emitted through the nozzles 6 Z) meets at a point midway between the nozzles and by reason of the angular convergence of the latter is constrained to expand outwardly in the form of a thin sheet of highly atomized ized directly upon the surface of respective branches 0; and o The material delivered upon thesurface of the branches aand a 1 will then flow down these branches until it reaches the point of atomization where it merges with the issuing pressure fluid'and is convertedthereby into the desired atoniized state. e I

In Fig. 3 the above described form is slightly modified in that a receptacle 9 is provided for retaining the fluid to be atomized and which latter is fed thereto through a valve h. This receptacle may be formed integral or otherwise with the main tube a.

3y reason of the provision of separate conveying tubes for the pressure fluid and liquid to be atomized, any of the examples herein described is eminently suitable for use in mixing liquids as well as atomizing them. i

What we claim is 1. An atomizer for liquids comprising a tube for conveying a gas under pressure, said tube having one end forked to form branches and the free ends of said branches being disposed in convergence, and means for delivering liquid to be atomized to the being disposed in convergence, a receptacle In testimony whereof We have signed our 10 for receiving the llquld to be atomized surnames to th1s speclficatlcn 1n the presence rounding said tube, and nozzles leading from of two subscrlblng wltnesses.

said receptacle and positioned to deliver the DAVID HIE-BERT THOMAS. material in the receptacle upon the surface ARTHUR DOUGLAS BERK.

of the branches of the first tube whereby FREDERICK JOHN MORGAN. said liquid will flow along said surfaces to Witnesses:

the point of atomization at the free ends of GILB RT NEs, 7

said branches. GEORGE MORRIS BAYNHAM.
